However,sequential follow-up of liver biochemical data remained lacking..METHODS: The biochemistry data and clinical symptoms of 11 sporadic patients were collected and analyzed, focusing on the impacts of leptospirosis upon liver biochemistry tests.RESULTS: The results disclosed that of the 11 cases, 5 or 45% died. The liver biochemistry data in the beginning of the disease course were only mildly elevated.Nevertheless, late exaggerated aspartate transaminase (AST)elevations were noted in three cases who finally died when compared with the typical course. Besides, significant higher AST/alanine transaminase (ALT) ratios (AARs) of the peak levels for transaminase were also noted in the cases who eventually succumbed. The mean±SD of AARs for the survival group and dead group were 5.65±2.27 (n = 5)and 1.86±0.64 (n = 6) respectively (P= 0.006). The ratios of the cases who finally died were all more than 3.0.Conversely, the survival group's ratios were less than 3.0.CONCLUSION: Serial follow-up of transaminase might provide evidence to predict some rare evolutions in leptospirosis. If AST elevated progressively without a concomitant change of ALT, it might indicate an acute disease course with ensuing death. Additionally, AAR is another prognostic parameter for leptospirosis. Once the value was higher than 3.0, a grave prognosis is inevitable.展开更多

The present study was aimed to investigate the cytoprotective activity of silymarin against diabetes-induced cardiomyocyte apoptosis. Methods Rats were randomly divided into： control group, untreated diabetes group and diabetes group treated with silymarin （120 mg/ks·d） for 10 d. Rats were sacrificed, and the cardiac muscle specimens and blood samples were collected. The immunoreactivity of caspase-3 and Bcl-2 in the cardiomyocytes was measured. Total proteins, glucose, insulin, creatinine, AST, ALT, cholesterol, and triglycerides levels were estimated. Results Unlike the treated diabetes group, cardiomyocyte apoptosis increased in the untreated rats, as evidenced by enhanced caspase-3 and declined Bcl-2 activities. The levels of glucose, creatinine, AST, ALT, cholesterol, and triglycerides declined in the treated rats. The declined levels of insulin were enhanced again after treatment of diabetic rats with silymarin, reflecting a restoration of the pancreatic β-cells activity. Conclusion The findings of this study are of great importance, which confirmed for the first time that treatment of diabetic subjects with silymarin may protect cardiomyocytes against apoptosis and promote survival-restoration of the pancreatic β-cells.展开更多
